Netcrypt- .NET executable packer

Netcrypt A proof-of-concept packer for .NET executables, designed to provide a starting point to explain the basic principles of runtime packing.

It is a full implementation of a simple .NET PE file packer, which doesn’t use native code, and with (almost) no noticeable delay during the unpacking phase of the application.

It can perform the following tasks:

  • pack itself
  • packing files packed by itself (up to four layers of packing are tested)
  • automagically resolve dependencies of the packed EXE
  • target multiple .NET versions (new!)

The following downsides/problems are known:

  • output files are quite big
  • there is no compression
  • console applications/DLLs cannot be packed.
